If all sides of a polygon have equal length, then the polygon is a regular polygon.

Which of the following is a counterexample to this conjecture?
A. a rhombus that does not have four right angles
B. a pentagon that has three congruent angles and three congruent sides
C. a quadrilateral that has four right angles
D. an equilateral triangle that is not equiangular

B

Step-by-step explanation:

bc if u do the correct equation that is what u should get

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
